Analogue Computers For Vehicles TRIZ Cases
- Lambda Controller Cold-Warm Adaptation Segmentation
Segmenting adaptation into cold and warm phases allows the lambda controller to maintain air-fuel ratio precision despite system tolerance variations.
- Position Sensor IC Short-Circuit Detection via Protective Resistors
Protective resistors create measurable voltage drops that enable detection of short-circuits between output terminals while limiting current flow.
- Engine Torque Control via Pressure Ratio and Inverted Models
A control method calculates desired throttle area using pressure ratio and inverted torque models for precise engine operation.
- Cursor Event Synchronization Across Multi-Window Geospatial Displays
Automatic cursor event synchronization transfers positioning data between sourcing and sourced windows for seamless multi-window navigation.
- Gas Turbine Engine Control for Blade Tip Clearance Deterioration
Controller calculates incremental deterioration values from engine measurement data to update accumulated blade wear metrics.
- Vehicle Throttle Control Stabilizing Phase Lead Compensator Noise
Relocating the noise filter to the output side of the phase lead compensator eliminates hunting fluctuations while maintaining fast system response.
- Vehicle Driving Force Controller with Mode Select Switch
A driving force control unit uses a multiple switch to select operating modes for vehicle power delivery.
- NOx Estimation Using Fuel Flow and Engine Parameters
Combines fuel flow rate with charge mass, temperature, and EGR fraction to estimate NOx production without dedicated sensors.
- Aircraft Ground Collision Avoidance via Conflict Cost Surfaces
A monitoring device evaluates aircraft positions using ADS-B networks to generate dynamic conflict cost surfaces for real-time pilot alerts.
